Yeelight Connexion interrupted

Hello,
When I try to connect my brand new yeelight to the android app (yeelight app or mi home) I get the error message “Connexion Interrupted”

Can you help me?
Thanks

Please have a check if your device in the DHCP list after it failed?

Hello,
Yes I can see the device listed after the failure

Thanks

Could you please try again and let me know the time you tried if you get same error.
